In python, please put comments for every function

Write a recursive function def reverse(string) that computes the reverse of a string. For example, reverse("flow") should return "wolf". Hint: Reverse the substring starting at the second character, then add the first character at the end. For example, to reverse "flow": Step 1 - reverse "low" to "wol", then add the "f" at the end Step 2 - repeat Step 1 for "low" - thus the recursive call Use these test cases: pineapple cherimoya (do you know what it is?
